2006 TBSS with 3000 stall. Is it normal that I do not reach a 12.5 afr till 3700 rpm? When I launch from idle to WOT my afr does not get to what I'd like till 3700 rpm.
I don't know if I should try to richen up below 3700 rpm? In the scan shot everything before 3700rpm is between 14.2-13.9 then it jumps to 12.5. Here is also a shot of my PE.
